ING-GUIDE FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 393,329, dated November20, 1888.

Application filed January 15, 1887. Serial No. 2.24.485.

To all whom it may concern.-

Be it known that I, HAYMAN FREEDMAN, of the city of Rochester, in thecounty of Monroe and State of New York, have invented a certain new anduseful Improvement in Tricking-Guides for Sewing-Machines; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the drawingsaccompanying this application.

This invention relates to an attachment for tucking thick and heavygoodssuch as woolen 'cl0thswhich are made up into childrens garments,and is especially for use in childrens clothing manufactories. It isfound that the ordinary plaiterssuch as accompany common sewing-machinesfor plaiting light goods-will not answer this purpose; hence it is thepractice in clothing-manufaetories to do the work by hand, first markingthe tucks with a measure, then folding and basting the tucks, andfinally stitching, each operation being complete in itself.

It is the object of my invention to obviate these difficulties byproducing a device by which the work can be done on a more expeditious,effective, and accurate manner.

In the drawings, Figure 1 is a plan view of the tucking attachmentlocated in the bed plate of a sewing-machine, showing also across-section of the needle-bar and presser-foot. Fig. 2 is a sideelevation of Fig. 1 looking in the direction of arrow 1,Fig. 1. Fig. 3is a longitudinal section in line 00 :20, Fig. 1. Fig. 4 is a rearelevation of Fig. 1, enlarged, looking in the direction of arrow 2, Fig.1.

A indicates the body of the device,the same consisting of a metal strapor plates provided at its left-hand end with a vertical flange, a, thatforms a guide, and also provided with a longitudinal slot, 1), for theattachment of the gage-bar and attaching-bar, as will presently bedescribed. The top surface of the plate A is laid .out in a scale ofinches and subdivisions, as shown,

13 is a gage-bar, and C an attaehing-bar,both standing at right anglesto the plate A, and secured thereto, on the under side by screws, onwhich are screw clamping-nuts d d. These bars are adjustable laterallyon the plate A to any desired position by simply loosening the (Nomodel.)

passes a thumb-screw, f, to attach the bar fast to the bed E of thesewing-machine, which is always provided with a hole to receive thescrew. This hole in the bed is at different places in differentmachines, and the object of the holes in the attachingbar, and also ofthe lateral adjustment of said bar on the plate A, is to fit the saidbar to the different positions of the hole in the plate, and also tobring the flange a in proper relative position with the needle G andprcsser-foot H. The object of adjusting the gagebar B laterally is toproduce different widths of tucks, as will presently be described. Thesquare edge of the gage-bar next to the needle serves as the shoulder orguide for the folded edge of the cloth to run against.

The operation is as follows: The left-hand edge of the cloth is firstfolded over, and then stitched up simply to forma rib, j, as thestarting-point of the tucking. This rib is placed outside of and againstthe vertical guide-flange a of the tucker. The gage-bar B is then movedinward or away from the needle a distance equal to the desired width ofthe tucks previously determined on. The loose end of the cloth is thendoubled under and turned back toward the left, which makes a fold in thecloth. In this condition the cloth is run through the sewing-machine,the ribj, previously formed, running against theflange a,and the loosefolded edge of the cloth running against the edge of the gage-bar B. Theneedle passes through the double folds of cloth intermediately betweenthe rib and the folded edge, as shown. This forms the tuck, which isthen turned up and is moved outward, and forms the rib that runs againstthe flange a in forming the second tuck. In this manner the tucks areall formed in succession, one after another, working from the left tothe right of the cloth. In ordinary tucking attachments now in use thetucks are made working from the right to the left. Very thick and heavygoods can be plaited by this attachment, which cannot be done byordinary tucker-s used with sewingmachines.

In very heavy goods it is necessary to hold the'folded edge down inadvance of the plate A, and opposite to the needle and presser-bar, sothat the fold will keep in contact with the edge of the gage-bar B;otherwise the cloth will spring up at that point and lose its holdagainst the gage-bar. I employ for this purposea spring, M, providedwith a slot, 8, by which it can be clamped and held by the thumb -screwf. The end 25 of this spring rests on the point of the presscr-foot, sothat it will rise and fall with the presser-foot to allow the cloth tobe fed along, and the spring is provided below the end twith abearingend, 1;, that bears on top of the cloth and holds it down at thepoint opposite the needle, so that it cannot rise above the edge of thegage-bar B. If desired,a shorter ire-enforcing spring, N, may be usedresting on top of the spring M.

Vhat I claim as new is In a tucking attachment for sewing-machines, thecombination of the plate A, provided with a guide-flange, a, restingoutside of theneedle, a gage-bar, B, attached to the plate restinginside of the needle, an attaching-bar, 0, provided with a series ofholes to attach the device to asewing-machinebed by a HAYMAN FREEDMAN.Witnesses:
